Question 1

What's the difference between a smartwatch and a sport watch — do I need both?

Accepted Answer

A smartwatch prioritises notifications, apps, and daily convenience; a sport watch prioritises training accuracy, GPS, and battery life. In 2026, the line has blurred considerably — Garmin's Venu series and Apple Watch handle both roles reasonably well. That said, if your primary goal is athletic performance, a dedicated sport watch like the Garmin Forerunner or Polar Pacer will give you better training data and far longer battery life than a general smartwatch. If you mostly want notifications with some fitness tracking on the side, a Samsung Galaxy Watch or Apple Watch is the more natural fit.

Question 2

Is Garmin really worth the premium over Amazfit or Xiaomi?

Accepted Answer

For serious training, yes — Garmin's ecosystem advantage is substantial. Garmin Connect offers training load analysis, recovery time estimates, VO2 max tracking, and structured workout support that Amazfit's Zepp app simply doesn't match in depth. However, if you're tracking steps, sleep, and casual runs rather than following a training plan, Amazfit and Xiaomi offer genuinely impressive hardware at a fraction of the price — often well below 89 £. The gap narrows if you don't use the advanced features.

Question 3

How much GPS battery life do I actually need?

Accepted Answer

For most runners and cyclists, 15–20 hours of GPS battery covers everything up to a full marathon or a long sportive. If you're training for ultras, Ironman-distance triathlons, or multi-day adventures, look for 30+ hours in standard GPS mode — or models with an ultra-trac/expedition mode that extends this further by reducing GPS polling frequency. The Garmin Tactix 7 and Fenix series are the benchmarks here. Don't be misled by standby battery figures, which can be 10× the GPS-on figure.

Question 4

Can I swim with a sport watch rated 5 ATM?

Accepted Answer

Yes — 5 ATM (50 metres) is the standard minimum for pool and open-water swimming, and the vast majority of sport watches above 89 £ meet this rating. What varies is whether the watch actually tracks swim metrics: stroke type, SWOLF score, lap counting. Check for dedicated swim modes rather than just the ATM rating. Avoid any watch rated only 3 ATM for swimming — it's splash-proof, not swim-proof, regardless of what the marketing implies.

Question 5

Are cheap smartwatches from unknown brands worth buying?

Accepted Answer

Generally, no — and this is the most common trap in this category. Watches below 89 £ from unrecognised brands often have inaccurate heart rate sensors, GPS that drifts badly, and companion apps that stop receiving updates within a year. The health data they produce can be actively misleading. If budget is tight, Amazfit and Xiaomi are the safe floor — both have genuine R&D behind their sensors and maintain their apps properly. Spending a little more here genuinely pays off.

Question 6

Does an Apple Watch work with Android phones?

Accepted Answer

No — Apple Watch requires an iPhone and is entirely incompatible with Android. This is a hard technical limitation, not a preference. If you're on Android, Samsung Galaxy Watch (best with Samsung phones but functional with most Android devices) or Google Pixel Watch are the closest equivalents. Garmin and Polar watches work well across both iOS and Android via their respective companion apps.

Question 7

What health metrics are actually useful versus marketing fluff?

Accepted Answer

Resting heart rate, heart rate variability (HRV), sleep staging, and VO2 max estimates are genuinely useful if you act on the data. SpO2 (blood oxygen) monitoring is less actionable for most people — it's accurate enough to flag obvious issues but not a substitute for medical-grade measurement. Stress scores and body battery metrics vary widely in accuracy between brands; Garmin's implementation is among the more reliable. Features like ECG are useful for those with specific cardiac concerns but require medical context to interpret properly.
